Dynamic enforcement of multi-api security policy at runtime
A recently granted patent (Publication Number: US11916964B2) discloses a computer-implemented method for dynamically enforcing a multi-API security policy at runtime. The method involves reading logs of calls to multiple APIs within a transaction, identifying data objects used by these APIs, assigning specific data labels to data fields, and constructing an API call graph to track the sequence of API calls. By utilizing specific data labels, the method consistently identifies data fields across multiple APIs, enabling the enforcement of a comprehensive security policy that covers various API calls within a transaction. The method also includes logging API calls at runtime, programmatically analyzing data objects, and utilizing linkages between APIs to determine service endpoints.
Furthermore, the patent describes the use of a linear regression model to determine neighbors of service endpoints and the enforcement of security policies to prohibit specific actions concerning identified data fields. The method does not require access to API specifications or code, making it versatile and applicable in various computing environments. By tracking the flow of execution during a multi-API transaction, the method can detect and respond to actions that violate the security policy in real-time. This includes blocking actions that attempt to gain unauthorized access to sensitive data, showcasing the method's proactive approach to ensuring data security within complex API transactions. The patent also covers computer-readable storage mediums and computer systems configured to implement this dynamic enforcement of multi-API security policies, highlighting the practical application of the disclosed method in real-world computing scenarios.
